In the following paper we will address the issues of new forms of filiation y consanguinity which rise up from assisted reproductive technologies (ARTs)
To do this, we will first considerer family as a form of organization in which this filial bonds takes place. Family understood from Levi’s Strauss anthropology and from the psychoanalytical perspective. Secondly, we will analyze the changes that the traditional family model has suffered and the changes in the different forms of filiation and consanguinity which arise as a result of the development of these techniques. Finally, we will mention some real and fictional cases which involve variations in family bonds, trying to assemble the concepts of identity and person, such us they were proposed by Agamben with the notion of subject in psychoanalytical terms analyzed by Lacan. Highlighting the crossroads presented in the fields of biology, law and psychoanalysis.
